В магазин канцтоваров привезли 187 пачек цветной бумаги по 18 листов в пачке и 5 пачек цветной бумаги по 28 листов в пачке. Для занятий в детском саду на месяц нужно 216 листов цветной бумаги. Нина Михайловна Купила все 5 пачек бумаги по 28 листов. Сколько еще пачек по 18 листов ей нужно купить, чтобы бумаги в детском саду хватило н месяц?

Ответы

Автор ответа: Margoritka1swetochek

5*28= 140 листов уже купила
216-140=76 листов еще купить
76:18=4.(2) примерно = 5 (округляем до целого, потому что нельзя купить пол пачки)
ответ: нужно купить еще 5 пачек бумаги по 18 листов
